Ngā aro ki te hanganga peita PU i te hotoke:

I. te taiao hangahanga

Kaua te pāmahana o te taiao hanga e iti iho i te 5 ℃, ā, kaua te haumākū e neke ake i te 80%.

Ina iti iho te pāmahana o roto i te 10 ℃, me mahi ngā mahi whakamahana tika hei whakarite i te tere maroke o te peita PU me te kore e pā ki te whai huatanga o te whakaputanga.

II. Kōwhiringa hua

1. Me whiriwhiri ngā hua i runga i te wā. Ko te tikanga, ka wehea te peita Pu ki te whakamahinga raumati me te whakamahinga hotoke. Kei runga i te tapanga o te tiwhikete whakaritenga (S) te whakamahinga raumati, ā, ko te (D) te whakamahinga hotoke. Ki te kore, ko te tikanga he whānui. Ina koa mō ngā hua paninga PU, i te ngahuru me te hotoke, kaua e whakamahia ngā hua raumati, ki te kore ka pāorooro te kanapa;

2. Me whakamahi te matū whakaora Pu e ōrite ana mō te peita PU, inā koa mō te paninga PU. Kaua e whakamahia te matū whakaora he iti te ihirangi totoka i te wā e pai ai, ki te kore ka kore e ranea te whakaora, ka nui te haunga toenga, ka ngoikore te tapahi, ka heke te kiriata peita, ka hē te kanapa, ka iti rānei te pakeke o te peita whakaoti, me ētahi atu;

4. Kōwhiringa whakarewa:

I te 15 ℃ – 20 ℃, ka tīpakohia te wai whakamāori paerewa Pu cj-001l, SR-71 rānei;

Ina iti iho te pāmahana i te 15 ℃, ka tīpakohia te wai whakamātao hotoke Pu cj-003l, sr-73 rānei.

III. te whakaranu peita

1. Nā te iti o te pāmahana i te takurua, ka puhoi haere te tere o te tauhohenga i waenga i te peita matua Pu me te matū whakamaroke. Ka taea te tāpiri atu i te 10% atu matū whakamaroke ki te wāhi hei whakapai ake i te pakeketanga me te piri o te rā e whai ake nei, ā, kāore e pā ki te kanapa o te paninga o runga. Ka tere ake te maroke o te paninga tuatahi.

2. I te takurua, kaua e neke atu i te 20% te nui o te tāpiri o te matū whakamaroke mō te paninga mārama PU, ā, kaua e neke atu i te 10% mō te paninga mā. Kaua e tāpiri atu i te matū whakamaroke i te hiahia hei whakapai ake i te tere maroke, ki te kore ka pakaru, ka ngoikore te piri, ka pakarukaru te kiriata peita, ka mā te peita i muri mai, me ētahi atu āhuatanga.

3. I muri i te whakaritenga o te paninga Pu me te paninga whakaoti, me pau i roto i ngā haora 3-4 (haunga te turanga mā, me pau i roto i ngā haora 2).

IV, ētahi atu

1. Mō te rauemi turanga he nui te hinu, he nui rānei te makuku, me whakahaere te makuku o te rakau mā te 8-12%, kātahi ka hiritia te rauemi turanga, ā, whakamahia te paninga hiri ātete-hinu Pu cj-104y hei ārai i te āhua mā o te kiriata peita. Hei tauira, me aro nui ki te tīki, te manga waikawa me te paina e mau ana i te hinu.

2. Hiri rauemi turanga noa: whakamahia te paninga hiri sr-201, cj-104 rānei hei whakarite i te pānga hiri.

3. Kāore i te tūtohutia kia whakamahia te paninga noa hei hiri i te papa i muri i te whakawairuatanga, ki te kore, kāore e ranea te mahi hiri, ka totohu pea te kiriata peita o muri mai, me ētahi atu. Heoi anō, kāore e taea te whakamahi i te kaihoko whakamaroke papatipu i te hiahia kia kore ai e pā ki te kanapa o te paninga o runga, te haunga o te kiriata peita, te kore e ranea te matotoru hononga o te kiriata peita, te pakarukaru rānei o te kiriata peita, te ngatata rānei; ka nui tonu te haunga o te kiriata peita i te wairewa papatipu, kāore e whakaaetia te kanapa, ā, ka pā ki te mārama o te kiriata peita, me ētahi atu.

4. Mena ka whakamahia te putty i roto i te hanganga, kaua e rakurakuhia, kaua hoki e pania kia matotoru rawa, ā, me whakakanapa rawa i muri i te maroke rawa, inā koa i roto i te tukanga peita totoka, kia kore ai e pakaru, e taka rānei.

5. Kāore e whakaaetia kia pania kotahi te matotoru i te wā e hangaia ana te papa hei ārai i te kohu o te kiriata, ā, kia kore ai e maroke te mata.
